▪ Abstract The use of stable isotope techniques in plant ecological research has grown
steadily during the past two decades. This trend will continue as investigators realize that …

Natural variations of the 13C/12C ratio have been frequently used over the last three
decades to trace C sources and fluxes between plants, microorganisms, and soil. Many of …

The increasing input of anthropogenically derived nitrogen (N) to ecosystems raises a
crucial question: how does available N modify the decomposer community and thus affects …

Permafrost contains about 50% of the global soil carbon. It is thought that the thawing of
permafrost can lead to a loss of soil carbon in the form of methane and carbon dioxide …

Recognition of biochar as a potential tool for long-term carbon sequestration with additional
agronomic benefits is growing. However, the functionality of biochar in soil and the response …

Abstract In this “Grand Challenges” paper, we review how the carbon isotopic composition of
atmospheric CO2 has changed since the Industrial Revolution due to human activities and …

Analyses of the natural variation in stable isotopes of components of ecological systems
have provided new insights into how these systems function across paleoecological to …

Leaf waxes (ie, n-alkyl lipids or n-alkanes) are land-plant biomarkers widely used to
reconstruct changes in climate and the carbon isotopic composition of the atmosphere …

Because atmospheric carbon dioxide is the ultimate source of all land-plant carbon, workers
have suggested that pCO2 level may exert control over the amount of 13C incorporated into …

Stable carbon isotopes are used extensively to examine physiological, ecological, and
biogeochemical processes related to ecosystem, regional, and global carbon cycles and …
